The thesis summarizes the history of enterprise application integration and shows the estimated benefits and risks that arise from attempts to harmonize corporate IT infrastructure. It also describes the main approaches to the integration and evaluates their resistance in terms of time. The thesis relates a modern interpretation of the integration of SOA (Service Oriented Architecture), including related standards. Particular attention is paid to the life cycle of services in SOA. It explains possible approaches and key principles of communication layer integrated business application system in terms of architectural design. The last part of the thesis examines for opportunities, risks and benefits of system application integration within the SOA implementation and assesses the economics of integration and the question of the investment protection.

<p>För att dagens system och deras allt mer komplexa applikationer ska kunna integreras med</p><p>varandra krävs det att de kommunicerar via tjänster. Denna tjänsteorienterade integration</p><p>uppnås genom att man använder sig av Service Oriented Architecture (SOA) som bygger på</p><p>löst kopplade tjänster som kommunicerar med varandra på ett standardiserat sätt. En viktig</p><p>del i en integrationslösning är Enterprise Service Bus (ESB). I denna rapport kommer vi</p><p>förklara grunderna i tjänsteorienterad integration och sedan fördjupa oss i ESB. Då ESB är ett</p><p>luddigt begrepp ska vi på ett enkelt och lättbegripligt sätt ge vår syn på begreppet, samt dess</p><p>fördelar och nackdelar. Vi kommer även att ge marknadens syn på ESB genom en</p><p>enkätundersökning som innefattar både leverantörer, konsulter och kunder.</p> / <p>If today’s software systems and their complex applications shall be able to integrate with each</p><p>other, they have to communicate through services. This service oriented integration can be</p><p>accomplished by using Service Oriented Architecture (SOA) where all components are</p><p>loosely coupled and communicate in a standardized way. An important part when building an</p><p>integrated solution is the Enterprise Service Bus (ESB). In this report we will explain the</p><p>basics of SOA and take a more detailed look at the world of ESB. The concept of ESB is not</p><p>well defined and hence means different things to different people. We are going to present an</p><p>interpretation of the ESB and its benefits and disadvantages.

<p>This thesis emphasizes on investigating the relationship between the quality attributes and service oriented architecture (SOA). Due to quality attributes requirements drive the design of software architecture, it is necessary to maintain the positive quality of SOA and improve the negative quality of SOA. This thesis gives an introduction to SOA, Enterprise Service Bus (ESB) and MULE. Then, it covers information on quality of systems and tactics for achieving each quality attribute. Finally, we discuss the quality of SOA in detail, and illustrate how to set up a SOA and how to improve its quality using a case of an order for supermarket.</p> / Order of supermarket

Virtual Organizations (VO)—a network of independent organizations collaborating to address specific business opportunities—have become popular in today’s technology driven business environment. Due to their autonomous and interdependent nature, management of collaboration among such organizations is a challenging task. Although many solutions have been proposed over the past two decades to support inter-organizational interactions, VOs still face several challenges due to their dynamic and temporal nature that cannot be addressed by traditional solutions such as ebXML, RosettaNet and EDI. In this research, we present a framework for process management in service oriented virtual organizations and a distributed architecture for a flexible infrastructure that supports collaborative business process execution, monitoring and management. The framework contains 6 layers with multiple components within each layer. In designing the components of the framework, standard reference architecture such as the Open-EDI reference model and the S3 service oriented architecture, as well as best practices such as ITIL V3 and PMBOK are used. The infrastructure supports the common topologies of inter-organizational collaboration (e.g. peer-to-peer, star, linear), and responds well to changes due to its loosely coupled components. The proposed infrastructure is based on federating multiple SOA infrastructures with the Enterprise Service Bus (ESB) as its core. It is implemented using IBM WebSphere ™ products. We demonstrate that VOs built with our framework and implementation architecture facilitate flexibility, rapid process integration and dynamic evolution.

Nowadays integration and interoperability can make or break an enterprise&apos;s business success. In the huge space that is software engi- neering a lot of ESBs have emerged but with vast di erences in imple- mentation, patterns and architectures. To create order in this disarray studies have been made, features eval- uated and performance measured. This is a good thing but it does not clear up all the confusion and adds another layer of confusion regarding the studies and tests themselves. The aim of this thesis is to make an attempt of rectifying some of the disorder by rst evaluating the current body of knowledge and to provide a humble attempt of making a transparent test framework which could be used for a more coherent ESB evaluation.

This bachelor thesis looks into the use Enterprise Service Bus(ESB) as the central hub in system integration, which is currently the newest standard for large-scale system integration. The thesis is focused on issues with ESB integration and solutions to these problems, as the positive aspects have already been covered in other reports. There is not much available information about the issues that can occur when using a ESB architecture and how to resolve thes issues. The contribution of this thesis is gathering known issues from both academic papers and from the industry and providing solutions to these issues. Also, we present a set of guidelines for developers that are new to ESB. These guidelines was formed by answers from a questionnaire that is in turn formed by a literature review, designed to nd issues with ESB integration. The solutions we found can be used by new ESB developers to avoid common mistakes and also might also assist by providing a solution in case an issue already har occurred.
